I have not seen any other production on the Hatfields and McCoys. I have nothing to compare it to other than history. This story goes from the beginning of the feud up until the pregnancy of Rosanna. It portrays the heads of both families, Devil Anse Hatfield (Jeff Fahey) and Ran'l McCoy (Perry King) as being honorable men. Christian Slater, who played the governor of Kentucky, wasn't as strong as the rest of the cast. The romance between Rosanna McCoy (Kassandra Clementi) and Johnse Hatfield (Sean Flynn) was poorly developed as we go from some flirting in the general store to a note to a full fledged romance. I will say that Kassandra Clementi in her role as Rosanna brought to mind Jennifer Lawrence in "Winter's Bone." This is perhaps the only bright spot of the film.
The fire on the roof was a CG effect. Doesn't anyone burn their sets anymore? The shooting of Asa McCoy by crazy Jim, was in part because he wore a Union uniform, but was also because Asa was college educated and had all kinds of different ideas. Yes, Jim Vance did shoot him, but nothing like it was shown.
This film fails as history. I won't go into details as to prevent plot spoilers, but it was inaccurate from beginning to end. If you want to feel like you are watching a western, this film will pass. It is loosely based on the historical tale.
